I'd just use dirEntries with SpanMode.shallow in combination

void foo(string path = "path")

if (e. isDir)
foo(e.name); // recurse

you will loop over all subdirs of "path" that satisfy 
`myCritreia`.


Thank you Nicolas. It's a good idea.

PS: With Linux find command, the thing can be done easily with 
`-prune` option:


```
find . -iname node_modules -prune
```

Without `-prune` option, there are a lot of unnecessary sub 
directories...

Hi,

Can I have a `break` option when using `dirEntries()`  (similar 
to `break` in a loop)? I want to study sub-directories but if 
any sub-directory matches my criteria I don't to look further 
into their subdirectories


```
  
 A/   -> matches criteria, stop here, go to next directory 
(B)
 B/   -> doesn't match criteria, will look at its 
sub-directories (BX, BY,...)

   BX
   BY
```

Thanks a lot
